The following videos illustrate the problem when extruding 2 faces in Maya.

Modo can handle the extrude but I cant seem to do the same in Maya

Maya Extrude

Modo Extrude

Thanks Guys

One thing you could try would be to turn "keep faces together" off and then merge the vertices together after?

modo does it different. it appears that it extrudes each face with the same "keep faces not together" method, but then it does not merge the verts in the center, but in the intersection of the connecting edges. not exactly sure how that would work if more than 2 faces meet in the to be merged vertex.

if you had exact knowledge of that you could try to write a script to simulate modos extrude in maya. i think mayas method of merging in the center is mathematically easier since it is independent of history and or location of neighboring elements.

and to make a long story short: maya does not have a extrude problem only b/c it does it different than modo. but then maya is not modo. otherwise the other way around modo has a extrude problem over maya. user added image

select the faces
click extrude
press r
hold d
snap pivot to opposite corner holding v
hold cntrl and click and hold on the red (x) handle
move the mouse and scale to whatever size you want.

does that work?
might only work once.

Hi clearairstudios,

To my knowledge, Maya does not have an extrude method that works like what you are seeing in Modo and even 3dsmax. Hopefully one day though it will as it would be very helpful especially for complex objects that are not symetrical in anyway. I like to use the method that stwert mentioned. I've never run into any geometry that it wouldn't work on, you just have to merge verts afterwards. It takes time but gives perfect results.

Don't be satisfied with what you can do but rather strive to do the things you can't do!
Exceed Expectations!

(or is this solution only for this specific problem and won't work universally on any extrudes?)

I think he's trying to describe this:

ah, this is specifically for that box video thing. that extrude problem is just a case of specific work arounds i believe.

. fair warning though - it is very sloooooow once your model reaches a lot of faces. wish they would add the option to mayas native extrude (e.g. called "preserve border edge offset"). also after using this plugin don't touch your history - or you will get really funky results ...
